I have IE 9.0.8112.16421
It opens links in the next tab.
<A href="http://msn.com" target="_blank">link</A>
<A href="http://jsfiddle.net/img/logo.png" target="_blank">image</A>
<span onclick="window.open('http://msn.com', 'openWindow', 'top=0, left=10, width = 500, height = 500,resizable=yes, location=yes, toolbar=yes, status=yes')" style="text-decoration:underline;color:blue;cursor:pointer;">linkJavascript</span>
And only in the third implementation, ONLY with params(Top, Left, Width etc) for window.open
javascript function, link was opened in the new window.
